Hub integration for 3rd party applications

It is possible for an application to create notification items that appear in the BB10 hub.

But is it also possible to create messages that appear in the hub with a custom application icon in a custom application folder? Or is this reserved for services like Twitter and Facebook and not open to developers?

So far I have only found sample code for notification integration into the hub.

This fires notifications, if you specify a title and body then the notification will also create an entry in the Hub. The next thing you want to do is add an InvokeRequest so that when the user selects the item in the Hub it actually does something (invoke your app to a certain page/state, invoke the browser etc).

You can get your InvokeRequest tested as well as Notifications (without the title and body) today then add in titles and bodies as soon as Hub is externally available.
